s 2, 3 and 5. Thanks!

Question 2 (2 points) Water is a bent molecule with polar covalent bonds that act like dipoles (a o+ and a o-). If the dipoles cancel out the molecule is nonpolar. If the dipoles don't cancel out the molecule has a net dipole and will act as a magnet. Another way to say this that symmetrical dipoles cancel out, and asymmetrical dipoles do not cancel out. Thus, water is asymmetrical and the dipoles do not cancel out. Therefore, water is a __1__ molecule, acts like a magnet, and is _2__ to other magnets. A. polar B. nonpolar C. attracted D. not attracted A/ A/ Question 3 (2 points) Water molecules are called __1__ molecules because they act like little magnets that stick together to form a liquid at room temperature. In contrast, __2__ molecules do NOT act like little magnets and do not stick together as a liquid, and are more likely to be a gas. Ammonia molecules are attracted to water, and dissolve in water, because ammonia is also a _ _3__ molecule. A polar bond is also called a dipole. Thus, both water and ammonia have dipoles as indicated by the difference in electronegativity, AEN. A. polar B. nonpolar Question 5 (2 points) The EN for H is __1__ and the EN for N is _2_ _. The N - H bonds in ammonia have a AEN = _3__. According to the AEN values in Chapter 10, the N-H bonds are _4__. Ammonia is pyramidal and is symmetrical/asymmetrical _5__. Therefore, ammonia is a polaronpolar _6__ molecule and behaves like a magnet. This explains why ammonia dissolves in water. A.
